Digital Output Terminals
Terminals accommodate wires up to 1.5 mm
2
(16 AWG). See the terminal torque specifications
on page
. Digital outputs (DO) are connected to these terminals.

TIP
Inductive loads can be connected without a protection diode on the load.
However, Rockwell Automation strongly recommends that a protection
diode be fitted directly to the load to suppress any interference voltage. A
1N4004 diode is recommended.
ATTENTION: Pulse outputs may not be used as safety-related outputs.
